Inventor Attorn eys Lisoseo.

To all whom t'z mag concern.

Be it known that I, Louis C. GREVEM- ing at Calumet, in the parish of St. Mary 5 and State of Louisiana, have invented a new and useful Settling rpparatus, of which the following is a specification.

This invention-relates to settlers or separators especially designed for use in the treatment of juices and liquids such as molass'es and syrups, one ofthe objects of the invention being to provide a settler made up of units so constructed and arranged that,

during the flow of the liquid therethrough, gases and vapors. carried by the liquid are free to rise promptly from the liquid to the external atmosphere or to a vacuum pump provided therefor, whereby their disturb ng influence of the light and flocculent precipitates' is greatly minimized, due to their rapid elimination from the volume of liquid.

Another object is to provide apparatus so constructed and arranged that the sediment carried by the liquid is precipitated through the liquid for a short distance only before coming to their point of discharge so that they are thus quickly removed from the currents of the liquid and can thus be more readily drawn offflthan otherwise.

A further object is to provide apparatus of this character which operates efiiciently to clear thetreated liquids because of the immediate removal of gases and vapors from said liquids upon entering the apparatus and the prompt settling of the sediment out of the path of the moving liquid- With the foregoing and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed, can be made within the scope of what is claimed, without departing from the spirit of the invention.

In the accompanying drawings the preferred form of the invention has been shown.

v In said drawings: Figure 1 is a side elevation of the apparatus. Fig. 2 is a rear elevation of the separating tanks, the supporting structure being removed. Fig. 3 is an benlarged longitudinal section through one Specification of Letters Patent.

ternal atmosphere or, if desired, a pipe 3 Y mayconnect the interior of the upper portion of the tank to like.

Anydesired number of tanks 1 may be used in the apparatus, these tanks being supported in inclined positions by any suitable structure indicated generally at 4. Each of the tanks is provided near the lower end thereof with an inlet pipe 5 provided with a T-shaped discharge nozzle 6 disposed in a plane extending longitudinally of the tank, one or" the outlets of the nozzle extending between the inlet pipe 5 and the lower end of the tank as shown. Another or. outlet pipe 7 is arranged within the tank near the top thereof and is also provided with a T-shaped portion 8 which constitutes a doua vacuum pump or the ble outlet for the liquid contents of the tank.

A supply pipe 9 extends to the inlet pipe 5 of the first tank and a connecting pipe 10 extends from the outlet pipe of said first tank to the inlet pipe of the second tank. This arrangement is continued throughout the length of the apparatus, the last tank of the series having its outlet pipe arranged to discharge the treated liquid wherever desired.

The drain pipes 2 are preferably provided with valves 11 of any construction desired for controlling the outflow of sediment.

In using the apparatus, the molasses, syrup or other liquid to be treated is directed through the pipe 9 into the inlet pipe 5 of the first tank and flows through the nozzle 6. By referring particularly to Fig. 1 it will be seen that as soon as the liquid enters the nozzle 6, any heavy sediment contained therein will promptly gravitate a short distance to the lowermost portion of the tank while at the same time, any gases or vapors commingled with the liquid will be free to escape upwardly within the tank 1 and to the external atmosphere or to the vacuum pump by way of the pipe 3. This prompt release. of the gases and vapors rom the liquid reduces to the minimum their disturbing influences on the light and flocculent precipitates contained within the liquid. As the sediment or precipitates in the liquid gravitate but short distancesto the lowermost portion of the tank, they are promptly removed from the current oithe inflowing liquid so that the danger. of this sediment or precipitate being carried out of the tank with the .outfiowlng liquid is minimized. As the liquid rises within the tank 1 it flows outwardly through the pipe 7 into fpipe 10 to the inlet pipe 5 of the next tank the area of the exposed surface, the more rapid and efiicient will be the separation of the gases and vapors from the liquid.

The several units can be connected by a pipe connecting the pipes 5, whereby clear liquid can be withdrawn from the apparatus in the event of extended delays. This pipe is shown at 11. It is to be understood that the form and location of the connection 11 can be varied or said connection can be entirely dispensed with if desired.

lVhat is claimed is 1. Separating apparatus of the class described, including an inclined tank having a sediment outlet in its lowest portion, means for directing liquid into the tank at a point adjacent said outlet, and means for withdrawing the liquid from the tank at a point adjacent the top thereof, there being an 011*- let above said lastnamed means for the escape of gas and vapor.

-2'. Apparat us of the class describedpin- OlUCllIlgfi; ser1es of inclined tanks-each having a liquid inlet adjacent the lowest portion thereof and a liquid outlet near the top thereof, the liquid outlet of one tank being in communication with the liquid inlet of the next adjoining tank, all of the: tanks.

having outlets at their upper end for the escape of gas and vapor, and means at the 7 lowest portion of each tankfor withdrawing sediment from the tank. 1

3. ilpparatus of the class described, in-

cluding a series of inclined tanks each hav- 'ing a liquid inlet adjacent the lowest portion'thereof and a liquid outlet near the top thereof, the liquid outlet of one tank being in communication withthe' liquid inlet of the next adjoining tank, all {of the tanks having outlets at their upper ends forthe escape of gas and-vapor, and means at the lowest portion of each tank for withdrawmg sediment from the-tank, said means being disposed under and close to the liquid inlet.
